To all 'whom t 'may concern:

vBe it known that l, WILLIAM Vieron Maren, a citizen of the UnitedStates, and resident of Milwaukee, in the county of Milwaukee and Stateof Wisconsin, have invented certain new and useful Improvements inPhonographs; and l do hereby declare that the following is a full,clear, and exact description thereof.

The invention relates to phonographs. llt comprises a base adapted to bepositioned on a disk record, a horn rotatable on the base, means forrotating the horn, a reproducer, and a telescopic tone arm axed to thehorn, the tone arm moving inwardl to colla ed position on the rotationof t e horn.

he primary object of the invention is the provision of a phonographoperating in an entirely new manner. rlhe record is entirely stationary,and the stylus and reproducer and parts cooperating immediately.

therewith are located onthe record, when the record is being played.

rlhe provision of a rotatable reproducer and tone arm is a markednovelty, thus the device is adapted to adord entertainment and may beused for purposes of advertisement, as its unusual principles ofoperation are adapted to attract considerable attention.

A further object of the invention is the provision of a phonogra h thatis small, all

arts lyin within the ace of an ordinary disk recor The tone arm iscollapsible, and may be positioned in the horn so that the device takesup a minimum of room, and maybe conveniently shipped and carried aboutfrom place to place.

A further object of the invention is the provision of anespeciallysimple structure easy to manufacture, made up of a minimumnumber of parts and inexpensive.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the novel construction,combination and arrangement of arts substantially as hereinafter deecrid and more particularlydened by the. appended claims, it beingunderstood that such changes in the-precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

In the accom anying drawing, is illus trated one com ete example of t ephysical embodiment o the present invention constructed according to thebest mode so far A base comprising a cylindrical wall and a dat bottom11 therefor, has a felt pad 12 secured to its bottom and adapted tocontact with a record disk 13 to prevent rotation of the base withrespect to the disk. lnteriorl dis osed and in contact with cylindricawal 10, is an annulus 14:,

having an interior ar 15 thereon, meshing with a gear 16 rigi withratchet 17, having a stub 18 rotatable in bottom l1. A crank 19 is shownin dotted lines, and may be applied on the .removal of record 13 to stub18 for the rotat1on of ear 16. rll`his operates to turn annulus 1t, w'ch, by pin 20, is secured to the end of a spiral spring 2l, the innerend of which is secured by pin 22 to a depending sleeve 23, which isrotatable on an inner sleeve 24, secured by pin 25 to shaft 26 which ismaintained stationary in the operation of the device. Sleeve 23 may beomitted.

Dog 27 cooperates with ratchet 17 to revent the release thereof, afterthe win ing of the spring. To play the record, sleeve 2d is inserted inthe openin in the record, and pad 12 is rested on t e face of therecord. 'ihe tension of the sprin acts thru sleeve 23, to rotate plate28 rigi with the sleeve. This operates to rotate cup-gear 29 secured toplat/e 28. rlhe cup-gear meshes with bevel gear 30 rigid with bevel gear31, the shaft for the bevel gears rotating in bracket 32, secured toshaft 26. Bevel gear 31 rotates bevel gear 33, which is provided with acollar 3d upwardly extending thru anv opening in diaphra m 35. llhediaphragm fits closely about t e collar, which is cyhndrical in shapebut cut away at opposite portions to receive the ends of springs 33which are maintained in Contact with dan phragm 35. .Diaphragm 35 isprovided with a circumferential depending flange 37, secured to cylinder38. The rotation of gear 3B-and collar 3ft operates thru the diaphragmto turn c linder 38. The cylinder is provided wit an opening, abovewhich a retaining band 39 is transversely disposed,

adapted to re'ceive a hook 40, rigid with section 41 of a tone arm. Thetone arm is made up of a plurality of telescopic sections, the outermostone 42 of which has an inwardly directed flange 43 received between bead44 and a collar 45 on U-tube 46, carrying re-l producer 47 and stylus48. The reproducer may be rotated about section 42 and brought adjacentto, or removed from, record 13. As the record is being layed, the tonearm is rotated, and sty us 48 travels in the I groove in lthe record,moving inwardly and collapsing the tone arm. Hook 40 provides a readymeans of aiiixation ofl the tone arm, and on removal of the arm,

it may be collapsed and positionedin cylinder 38 so that it will take upa. minlmum of room, and may be easily shipped and transported from placeto place.

The sounds transmitted thru the tone arm are received in the cylinder38, and directed outwardly by a truncated cone 49, the large bottom ofwhich is provided with a lateral flange 50, carryin a felt pad 51. Shaft26 extends up'war ly thru cylinder' 38, and has a threaded portion 52.An elongated brake 53 is threaded on this portion, its upper end beingknurled to facilitate manual adjustment. Cone 49 is flattened at 1tsupp'er end. A spring 54 envelops shaft 26 immediately adjacent the upperend of the cone, the spring being supported by shoulder 55 carried bythe shaft. When brake 53 is rotated to move downwardly, pad 51 on cone49 is brought in contact with diahragm 35. This prevents rotation ofcyllnder 38 with respect to the shaft. On the movement u wardly of brake53, pad 51 is removed rom diaphragm 35, spring 54 operating to move cone49 upwardly. Brake 53 may be used at any time at which a brake on 'theordinary phonograph is o erated. Cylinder 38 operates substantial y as ahorn as the sound waves expand in traveling outwardly ybetween thecylinder and cone 49.

Cone 49 is threaded at 56 to receive an adjuster rod 57, having a head58 at its lower end. The rod has a knurled handle 59, which may berotated bv the fingers to raise or lower the head 58. Springs 36 haveweights 60 intermediate their ends, and are outwardly disposed. Theup'per ends of the springs are secured to a collar 61, which is rigidwith a disk 62. In the playing of the record, diaphragm 35, springs 36,

weights 60, collar, 61 and disk 62 are ro-f'uv tated. The rotation ofthese parts tends to move weights 60foutwardly against the acrecord.

tion of the springs 36. This causes a down- 60 ward movement of collar61 and disk 62. Obviously the greater the speed of rotation, the greaterthe distance of movement of disk 62. If disk 62 is brought in contactwith head 58, the frictional action of the parts tends vto retard therotation. Thus-.the speed will be decreased until the disk 62 isscarcely in ycontact with the head 58. It is apparent therefore, -thatby re lating the` height of the head 58, the sp of rotation of disk 62,and consequently of the cylinder 3.8, maybe controlled.

I claim:

1. The combination of a record and a phonograph located entirel abovesaid record and opferable on saidY record while said record isstationary for reproducin the sound recorded by said record Saidphonograph being supported entirely by said record.

2. The combination of a member adapted to rest centrally upon a discrecord, a tone arm,a reproducer on said arm and means co-operating withsaid member and said arm to rotate said arm for reproducing the soundrecorded by said record.

3. The combination of a member adapted to 'be inserted into the openingin a disc record, a tone arm and reproducer on said arm and means forrotating said tone arm, said member cooperating with said means and saidtone arm to Amaintain said means and said tone arm in position on said4. The combination of a disk record, a base thereon, ahorn rotatable onsaid base, means for rotating said horn, a tone arm secured to the sideof said horn and rotatable therewith, said horn having an" openingtherein for the transmission of sound from said tone arm, a conicalmember in said horn, a rigid -member secured tosaid horn and adapted tocooperate in one ition with said conical member for retar ing therotation of said horn, and means for controlling the position of saidconical member.

5. In a device of the class described, the combination of a base adaptedto rest on a. record, a cylinder having an opening therein rotatable onsaid base, a telescopic tone arm secured to said cylinder at saidopening and a reproducer on said tone arm.

In testimony that I 'claim-the foregoing I have hereunto set my hand atMilwaukee Wisconsin.
